It is now possible to include a set of default ngcc configurations
that ship with ngcc out of the box. This allows ngcc to handle a
set of common packages, which are unlikely to be fixed, without
requiring the application developer to write their own configuration
for them.
Any packages that are configured at the package or project level
will override these default configurations. This allows a reasonable

Currently Ivy stores the element attributes into an array above the component def and passes it into the relevant instructions, however the problem is that upon minification the array will get a unique name which won't compress very well.

With #31953 we moved the factories for components, directives and pipes into a new field called `ngFactoryDef`, however I decided not to do it for injectables, because they needed some extra logic. These changes set up the `ngFactoryDef` for injectables as well.
For reference, the extra logic mentioned above is that for injectables we have two code paths:
1. For injectables that don't configure how they should be instantiated, we create a `factory` that proxies to `ngFactoryDef`:
```
// Source
@Injectable()
class Service {}
// Output
class Service {
static ngInjectableDef = defineInjectable({
factory: () => Service.ngFactoryFn(),
});
static ngFactoryFn: (t) => new (t || Service)();
}
```
2. For injectables that do configure how they're created, we keep the `ngFactoryDef` and generate the factory based on the metadata:
```
// Source
@Injectable({
useValue: DEFAULT_IMPL,
})
class Service {}
// Output
export class Service {
static ngInjectableDef = defineInjectable({
factory: () => DEFAULT_IMPL,

Recently ng-packagr was updated to include a transform that used to be
done in tsickle (https://github.com/ng-packagr/ng-packagr/pull/1401),
where only constructor parameter decorators are emitted in tsickle's
format, not any of the other decorators.
ngcc used to extract decorators from only a single format, so once it
saw the `ctorParameters` static property it assumed the library is using
the tsickle format. Therefore, none of the `__decorate` calls were
considered. This resulted in missing decorator information, preventing
proper processing of a package.
This commit changes how decorators are extracted by always looking at
both the static properties and the `__decorate` calls, merging these
sources appropriately.

ngcc may need to insert public exports into the bundle's source as well
as to the entry-point's declaration file, as the Ivy compiler may need
to create import statements to internal library types. The way ngcc
knows which exports to add is through the references registry, to which
references to things that require a public export are added by the
various analysis steps that are executed.
One of these analysis steps is the augmentation of declaration files
where functions that return `ModuleWithProviders` are updated so that a
generic type argument is added that corresponds with the `NgModule` that
is actually imported. This type has to be publicly exported, so the
analyzer step has to add the module type to the references registry.
A problem occurs when `ModuleWithProviders` already has a generic type
argument, in which case no update of the declaration file is necessary.
This may happen when 1) ngcc is processing additional bundle formats, so
that the declaration file has already been updated while processing the
first bundle format, or 2) when a package is processed which already
contains the generic type in its source. In both scenarios it may occur
that the referenced `NgModule` type does not yet have a public export,
so it is crucial that a reference to the type is added to the
references registry, which ngcc failed to do.
This commit fixes the issue by always adding the referenced `NgModule`
type to the references registry, so that a public export will always be
created if necessary.

In ngcc's reflection host for UMD and CommonJS bundles, custom logic is
present to resolve import details of an identifier. However, this custom
logic is unable to resolve an import for an identifier inside of
declaration files, as such files use the regular ESM import syntax.
As a consequence of this limitation, ngtsc is unable to resolve
`ModuleWithProviders` imports that are declared in an external library.
In that situation, ngtsc determines the type of the actual `NgModule`
that is imported, by looking in the library's declaration files for the
generic type argument on `ModuleWithProviders`. In this process, ngtsc
resolves the import for the `ModuleWithProviders` identifier to verify
that it is indeed the `ModuleWithProviders` type from `@angular/core`.
So, when the UMD reflection host was in use this resolution would fail,
therefore no `NgModule` type could be detected.
This commit fixes the bug by using the regular import resolution logic
in addition to the custom resolution logic that is required for UMD
and CommonJS bundles.

In ESM2015 bundles, a class with decorators may be emitted as follows:
```javascript
var MyClass_1;
let MyClass = MyClass_1 = class MyClass {};
MyClass.decorators = [/* here be decorators */];
```
Such a class has two declarations: the publicly visible `let MyClass`
and the implementation `class MyClass {}` node. In #32539 a refactoring
took place to handle such classes more consistently, however the logic
to find static properties was mistakenly kept identical to its broken
state before the refactor, by looking for static properties on the
implementation symbol (the one for `class MyClass {}`) whereas the
static properties need to be obtained from the symbol corresponding with
the `let MyClass` declaration, as that is where the `decorators`
property is assigned to in the example above.
This commit fixes the behavior by looking for static properties on the
public declaration symbol. This fixes an issue where decorators were not
found for classes that do in fact have decorators, therefore preventing
the classes from being compiled for Ivy.

In ngcc's reflection hosts for compiled JS bundles, such as ESM2015,
special care needs to be taken for classes as there may be an outer
declaration (referred to as "declaration") and an inner declaration
(referred to as "implementation") for a given class. Therefore, there
will also be two `ts.Symbol`s bound per class, and ngcc needs to switch
between those declarations and symbols depending on where certain
information can be found.
Prior to this commit, the `NgccReflectionHost` interface had methods
`getClassSymbol` and `findClassSymbols` that would return a `ts.Symbol`.
These class symbols would be used to kick off compilation of components
using ngtsc, so it is important for these symbols to correspond with the
publicly visible outer declaration of the class. However, the ESM2015
reflection host used to return the `ts.Symbol` for the inner
declaration, if the class was declared as follows:
```javascript
var MyClass = class MyClass {};
```
For the above code, `Esm2015ReflectionHost.getClassSymbol` would return
the `ts.Symbol` corresponding with the `class MyClass {}` declaration,
whereas it should have corresponded with the `var MyClass` declaration.
As a consequence, no `NgModule` could be resolved for the component, so
no components/directives would be in scope for the component. This
resulted in errors during runtime.
This commit resolves the issue by introducing a `NgccClassSymbol` that
contains references to both the outer and inner `ts.Symbol`, instead of
just a single `ts.Symbol`. This avoids the unclarity of whether a
`ts.Symbol` corresponds with the outer or inner declaration.

`ngcc` supports both synchronous and asynchronous execution. The default
mode when using `ngcc` programmatically (which is how `@angular/cli` is
using it) is synchronous. When running `ngcc` from the command line
(i.e. via the `ivy-ngcc` script), it runs in async mode.
Previously, the work would be executed in the same way in both modes.
This commit improves the performance of `ngcc` in async mode by
processing tasks in parallel on multiple processes. It uses the Node.js
built-in [`cluster` module](https://nodejs.org/api/cluster.html) to
launch a cluster of Node.js processes and take advantage of multi-core
systems.
Preliminary comparisons indicate a 1.8x to 2.6x speed improvement when
processing the angular.io app (apparently depending on the OS, number of
available cores, system load, etc.). Further investigation is needed to
better understand these numbers and identify potential areas of
improvement.

processing of each entry-point. This metadata was stored in a `Map`, in
the form of `EntryPointProcessingMetadata` and passed around as needed.
After some recent refactorings, it turns out that this metadata (with
its only remaining property, `hasProcessedTypings`) was no longer used,

In the past, a task's processability didn't use to be known in advance.
It was possible that a task would be created and added to the queue
during the analysis phase and then later (during the compilation phase)
it would be found out that the task (i.e. the associated format
property) was not processable.
As a result, certain checks had to be delayed, until a task's processing
had started or even until all tasks had been processed. Examples of
checks that had to be delayed are:
- Whether a task can be skipped due to `compileAllFormats: false`.
- Whether there were entry-points for which no format at all was
successfully processed.
It turns out that (as made clear by the refactoring in 9537b2ff8), once
a task starts being processed it is expected to either complete
successfully (with the associated format being processed) or throw an
error (in which case the process will exit). In other words, a task's
processability is known in advance.
This commit takes advantage of this fact by moving certain checks
earlier in the process (e.g. in the analysis phase instead of the
compilation phase), which in turn allows avoiding some unnecessary work.
More specifically:
- When `compileAllFormats` is `false`, tasks are created _only_ for the
first suitable format property for each entry-point, since the rest of
the tasks would have been skipped during the compilation phase anyway.
This has the following advantages:
1. It avoids the slight overhead of generating extraneous tasks and
then starting to process them (before realizing they should be
skipped).
2. In a potential future parallel execution mode, unnecessary tasks
might start being processed at the same time as the first (useful)
task, even if their output would be later discarded, wasting
resources. Alternatively, extra logic would have to be added to
prevent this from happening. The change in this commit avoids these
issues.
- When an entry-point is not processable, an error will be thrown
upfront without having to wait for other tasks to be processed before
failing.

Previously, `ngcc`'s programmatic API would run and complete
synchronously. This was necessary for specific usecases (such as how the
`@angular/cli` invokes `ngcc` as part of the TypeScript module
resolution process), but not for others (e.g. running `ivy-ngcc` as a
`postinstall` script).
This commit adds a new option (`async`) that enables turning on
asynchronous execution. I.e. it signals that the caller is OK with the
function call to complete asynchronously, which allows `ngcc` to
potentially run in a more efficient mode.
Currently, there is no difference in the way tasks are executed in sync
vs async mode, but this change sets the ground for adding new execution
options (that require asynchronous operation), such as processing tasks
in parallel on multiple processes.
NOTE:
When using the programmatic API, the default value for `async` is
`false`, thus retaining backwards compatibility.
When running `ngcc` from the command line (i.e. via the `ivy-ngcc`
script), it runs in async mode (to be able to take advantage of future
optimizations), but that is transparent to the caller.

When ngcc is called for a specific entry-point, it has to determine
which dependencies to transitively process. To accomplish this, ngcc
traverses the full import graph of the entry-points it encounters, for
which it uses a dependency host to find all module imports. Since
imports look different in the various bundle formats ngcc supports, a
specific dependency host is used depending on the information provided
in an entry-points `package.json` file. If there's not enough
information in the `package.json` file for ngcc to be able to determine
which dependency host to use, ngcc would fail with an error.
If, however, the entry-point is not compiled by Angular, it is not
necessary to process any of its dependencies. None of them can have
been compiled by Angular so ngcc does not need to know about them.
Therefore, this commit changes the behavior to avoid recursing into
dependencies of entry-points that are not compiled by Angular.
In particular, this fixes an issue for packages that have dependencies
on the `date-fns` package. This package has various secondary
entry-points that have a `package.json` file only containing a `typings`
field, without providing additional fields for ngcc to know which
dependency host to use. By not needing a dependency host at all, the
error is avoided.

Previously, `ngcc` assumed that if a format property was defined in
`package.json` it would point to a valid format-path (i.e. a file that
is an entry-point for a specific format). This is generally the case,
except if a format property is set to a non-string value (such as
`package.json`) - either directly in the `package.json` (which is unusual)
or in ngcc.config.js (which is a valid usecase, when one wants a
format property to be ignored by `ngcc`).
For example, the following config file would cause `ngcc` to throw:

During the dependency analysis phase of ngcc, imports are resolved to
files on disk according to certain module resolution rules. Since module
specifiers are typically missing extensions, or can refer to index.js
barrel files within a directory, the module resolver attempts several
postfixes when searching for a module import on disk. Module specifiers
that already include an extension, however, would fail to be resolved as
ngcc's module resolver failed to check the location on disk without
adding any postfixes.
Closes#32097

During the recursive processing of dependencies, ngcc resolves the
requested file to an actual location on disk, by testing various
extensions. For recursive calls however, the path is known to have been
resolved in the module resolver. Therefore, it is safe to move the path
resolution to the initial caller into the recursive process.
Note that this is not expected to improve the performance of ngcc, as
the call to `resolveFileWithPostfixes` is known to succeed immediately,
as the provided path is known to exist without needing to add any
postfixes. Furthermore, the FileSystem caches whether files exist, so
the additional check that we used to do was cheap.

ngcc needs to solve a unique problem when compiling typings for an
entrypoint: it must resolve a declaration within a .js file to its
representation in a .d.ts file. Since such .d.ts files can be used in deep
imports without ever being referenced from the "root" .d.ts, it's not enough
to simply match exported types to the root .d.ts. ngcc must build an index
of all .d.ts files.
Previously, this operation had a bug: it scanned all .d.ts files in the
.d.ts program, not only those within the package. Thus, if a class in the
program happened to share a name with a class exported from a dependency's
.d.ts, ngcc might accidentally modify the wrong .d.ts file, causing a
variety of issues downstream.
To fix this issue, ngcc's .d.ts scanner now limits the .d.ts files it
indexes to only those declared in the current package.

One of the compiler's tasks is to enumerate the exports of a given ES
module. This can happen for example to resolve `foo.bar` where `foo` is a
namespace import:
```typescript
import * as foo from './foo';
@NgModule({
directives: [foo.DIRECTIVES],
})
```
In this case, the compiler must enumerate the exports of `foo.ts` in order
to evaluate the expression `foo.DIRECTIVES`.
When this operation occurs under ngcc, it must deal with the different
module formats and types of exports that occur. In commonjs code, a problem
arises when certain exports are downleveled.
```typescript
export const DIRECTIVES = [
FooDir,
BarDir,
];
```
can be downleveled to:
```javascript
exports.DIRECTIVES = [
FooDir,
BarDir,
```
Previously, ngtsc and ngcc expected that any export would have an associated
`ts.Declaration` node. `export class`, `export function`, etc. all retain
`ts.Declaration`s even when downleveled. But the `export const` construct
above does not. Therefore, ngcc would not detect `DIRECTIVES` as an export
of `foo.ts`, and the evaluation of `foo.DIRECTIVES` would therefore fail.
To solve this problem, the core concept of an exported `Declaration`
according to the `ReflectionHost` API is split into a `ConcreteDeclaration`
which has a `ts.Declaration`, and an `InlineDeclaration` which instead has
a `ts.Expression`. Differentiating between these allows ngcc to return an
`InlineDeclaration` for `DIRECTIVES` and correctly keep track of this
export.
